Available in PDF, EPUB and Kindle. Book excerpt: The steady-state and transient gas release and swelling subroutine (GRASS-SST) is a mechanistic computer code for the prediction of fission-gas behavior in UO2-base fuels. GRASS-SST treats fission-gas release and fuel swelling on an equal basis and simultaneously treats all major mechanisms that influence fission-gas behavior. The GRASS-SST transient analysis has evolved through comparisons of code predictions with the fission-gas release and physical phenomena that occur during reactor operation and transient direct-electrical heating (DEH) testing of irradiated light-water reactor fuel. The GRASS-SST steady-state analysis has undergone verification for end-of-life fission-gas release and intragranular bubble-size distributions. The results of GRASS-SST predictions for transient fission-gas release during DEH tests are in good agreement with experimental data.

Available in PDF, EPUB and Kindle. Book excerpt: A theoretical model (FASTGRASS) has been used for predicting the behavior of fission gas and volatile fission products (VFPs) in UO2-base fuels during steady-state and transient conditions. This model represents an attempt to develop an efficient predictive capability for the full range of possible reactor operating conditions. Fission products released from the fuel are assumed to reach the fuel surface by successively diffusing (via atomic and gas-bubble mobility) from the grains to grain faces and then to the grain edges, where the fission products are released through a network of interconnected tunnels of fission-gas-induced and fabricated porosity.

This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A discussion is presented on the interplay between mechanisms of fission-gas behavior, and on how the assumed relationships between various mechanisms affect predictions for the behavior of the gas during a wide range of operating conditions. Highlighted in the discussion are the relationships between intragranular fission gas mobilities during normal and off-normal (nonequilibrium) conditions and intra- and intergranular gas-atom re-solution. The main conclusion reached is that more definitive information about the nature of the mechanisms and about the synergistic relationship between them await further experiments and analyses of the observed phenomena.
Download or read book Fission Gas Release from UO sub 2 x in Defective Light Water Reactor Fuel Rods written by and published by . This book was released on 1999 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simplified semi-empirical model predicting fission gas release form UO{sub 2+x} fuel to the fuel rod plenum as a function of stoichiometry excess (x) is developed to apply to the fuel of a defective LWR fuel rod in operation. The effect of fuel oxidation in enhancing gas diffusion is included as a parabolic dependence of the stoichiometry excess. The increase of fission gas release in a defective BWR fuel rod is at the most 3 times higher than in an intact fuel rod because of small extent of UO2 oxidation. The major enhancement contributor in fission gas release of UO{sub 2+x} fuel is the increased diffusivity due to stoichiometry excess rather than the higher temperature caused by degraded fuel thermal conductivity.

This model represents an attempt to develop an efficient predictive capability for the full range of possible reactor operating conditions.

The model provides for a multi-region calculation and uses only one size class to characterize a distribution of fission gas bubbles.
